To analyze whether a Dust-based weapon could theoretically hold or restrain Salem and potentially send her off-world, we need to consider the properties of Dust, Salem’s nature, and the limitations of Dust as described in the provided RWBY wiki information. Below is a speculative analysis based on the wiki data:
Nature of Dust: Dust is a naturally occurring energy propellant in Remnant, triggered by the Aura of Humans and Faunus. It exists in crystalline, powdered, and bullet forms, and is highly versatile, used for combat, powering technology, and mundane purposes.
Types of Dust: Dust comes in various forms, including primary types (Fire, Water, Electricity, Wind) and combination types (e.g., Ice, Gravity, Hard-Light). Each type has unique properties, such as Gravity Dust manipulating gravitational fields or Hard-Light Dust creating solid light constructs.
Limitations: Dust does not function outside Remnant’s atmosphere, precluding space flight. However, it works in the Ever After, a different realm, suggesting some environmental dependency (possibly oxygen, as speculated in the wiki’s trivia).
Combat Applications: Dust can be used in weapons (e.g., Weiss’s Myrtenaster, Ruby’s Crescent Rose), infused into the body (e.g., Hazel’s method), woven into clothing, or used raw. It can enhance Semblances, create elemental effects, or power advanced technology like shields or vehicles.
Immortality: Salem is immortal, as established in “The Lost Fable.” She cannot be killed, and her body regenerates from any damage.
Magical Nature: Unlike most inhabitants of Remnant, Salem possesses true magic, a power predating Dust and not reliant on Aura. This makes her fundamentally different from Humans and Faunus, who rely on Dust and Aura.
Interaction with Dust: While Dust is typically activated by Aura, the wiki notes that Gravity Dust in Monstra (Salem’s Grimm whale) allowed flight without clear Aura activation, suggesting Dust might function differently in certain contexts or with Grimm.
Analysis: Could a Dust Weapon Hold Salem?
To hold or restrain Salem, a Dust-based weapon would need to:
Overpower or Restrain Her: Create a containment strong enough to counter her magical abilities and physical resilience.
Neutralize Her Magic: Prevent her from using magic to escape or counter the restraint.
Sustain the Effect: Maintain containment long enough to achieve the goal (e.g., sending her off-world).
Potential Dust Types for Restraining Salem
Properties: Forms solid light constructs, such as shields or barriers, and is used in advanced technology (e.g., Amity Colosseum’s shields, Atlas’s defenses).
Feasibility: Hard-Light Dust could theoretically create a containment field or cage to trap Salem. Its ability to form solid objects might restrain her physically, but her magical abilities could potentially disrupt or destroy such constructs, as she wields power beyond Aura-based Dust activation. The wiki notes Hard-Light Dust is rare and primarily produced by the Schnee Dust Company, so supply limitations could be an issue.
Limitations: Hard-Light constructs are not indestructible (e.g., James Ironwood’s arm was burned by Hard-Light Dust in a fight). Salem’s magic might overpower or destabilize the constructs, especially since she can manipulate Grimm and environmental factors.
Properties: Manipulates gravitational fields to pull or push objects, create levitation, or enhance weapon impacts. It was used to make Monstra fly and powers floating structures like Atlas (via the Relic of Creation cover story).
Feasibility: Gravity Dust could theoretically pin Salem in place by creating an intense gravitational field or levitate her to isolate her from the ground or allies. The wiki mentions Gravity Dust’s ability to push outward, which could counter her movements. However, her magical abilities might allow her to counteract gravitational manipulation, especially since Monstra’s flight suggests Dust can function in unconventional ways under her influence.
Limitations: Gravity Dust’s effects are not absolute, and Salem’s magic could potentially disrupt the gravitational field. Additionally, maintaining a strong enough field to hold her would require significant Dust reserves and precise control.
Properties: Creates ice structures (e.g., crystals, sheets, ramps) to trap or immobilize enemies, as seen with Weiss’s use in “Players and Pieces” and “No Brakes.”
Feasibility: Ice Dust could encase Salem in ice to temporarily immobilize her. Weiss has used it to trap powerful enemies like the Death Stalker, suggesting potential effectiveness. However, Salem’s regenerative abilities and magic could allow her to break free or melt the ice (especially if she counters with Fire or Lava Dust-like effects).
Limitations: Ice is fragile compared to Salem’s power, and her immortality means temporary immobilization would not be a long-term solution.
Combination Dust with Semblances:
Properties: Dust can enhance Semblances (e.g., Weiss’s Time Dilation with Lightning Dust, Blake’s elemental Shadow clones). A skilled Huntsman or Huntress with a powerful Semblance could use Dust to create a unique restraining effect.
Feasibility: A Semblance like Weiss’s glyphs, enhanced with Hard-Light or Gravity Dust, might create a more complex containment field (e.g., a glyph-based prison). However, Salem’s magic likely surpasses Semblance-based abilities, as she predates the Aura-based system.
Limitations: The effectiveness depends on the user’s skill and Aura reserves, which may not match Salem’s limitless magical power.
The goal of sending Salem off-world introduces additional challenges:
Dust’s Atmospheric Limitation: The wiki explicitly states that Dust does not function outside Remnant’s atmosphere, ruling out its use for space travel or off-world containment. A Dust-powered weapon or vehicle (e.g., using Gravity Dust for propulsion) would cease functioning once it leaves Remnant’s atmosphere, making it impossible to send Salem into space using Dust alone.
Alternative Realms (e.g., Ever After): Dust functions in the Ever After, as noted in the wiki. Theoretically, a Dust-based weapon could be used to transport Salem to another realm if a portal or similar mechanism exists (e.g., the Vaults or Ambrosius’s abilities). However, this would require a non-Dust method to open such a portal, as Dust alone cannot create interdimensional travel.
Containment During Transport: Even if a portal to another realm were opened, restraining Salem long enough to force her through would be difficult. Her magic and immortality make her resistant to physical and elemental restraints, and she could potentially summon Grimm or use magic to escape.
Hard-Light Containment Field: A team of Huntsmen could use Hard-Light Dust to create a temporary barrier around Salem, reinforced by Gravity Dust to anchor her. This might hold her briefly, but her magic could destabilize the field, especially if she summons Grimm to attack it.
Gravity Dust Levitation: A weapon using Gravity Dust could lift Salem into the air, isolating her from the ground. If combined with a portal to the Ever After (created by non-Dust means, like the Relic of Creation), she could theoretically be sent to another realm. However, Dust’s atmospheric limitation prevents space travel.
Semblance-Enhanced Dust Trap: A character with a powerful Semblance (e.g., Weiss or Blake) could use Dust to create a complex trap, such as a Hard-Light glyph cage or Ice Dust prison. However, Salem’s magic would likely overpower these efforts unless multiple skilled users coordinated their attacks.
Monstra-Like Application: Since Monstra used Gravity Dust to fly, a similar Dust-powered construct could be designed to trap and transport Salem. However, this would require Salem’s cooperation or a way to override her control, which is unlikely given her magical dominance.
Challenges and Limitations
Salem’s Magic: Her true magic surpasses Aura-based Dust activation, making it unlikely that Dust alone could restrain her for long. Her ability to manipulate Grimm and her environment (e.g., Monstra’s flight) suggests she could counter Dust effects.
Immortality: Even if restrained, Salem cannot be permanently defeated, so any containment would be temporary unless she is sent to a realm where her magic is neutralized (an unknown factor).
Dust Supply: Restraining a being as powerful as Salem would require vast amounts of Dust, especially rare types like Hard-Light. The destruction of the Schnee Dust Company and Atlas’s Dust reserves (post-Volume 8) limits availability.
Atmospheric Constraint: The inability of Dust to function outside Remnant’s atmosphere makes off-world transport via Dust impossible without an external mechanism (e.g., a relic or magical portal).
A Dust-based weapon could theoretically restrain Salem temporarily using Hard-Light Dust for barriers, Gravity Dust for immobilization, or Ice Dust for encasement, especially if combined with powerful Semblances. However, her immortality and magical abilities make long-term containment highly unlikely. Sending her off-world is not feasible with Dust alone due to its atmospheric limitation, though transport to another realm like the Ever After might be possible if a portal mechanism exists. The most viable approach would involve combining Dust-based weapons with non-Dust methods (e.g., relics or divine intervention) to exploit Salem’s weaknesses, but no Dust weapon alone could achieve this goal based on current wiki information.
