[various maintenance sketches]
[due to his severe overload, a condition where a monster generates too much magic, sans has a portable drain attached directly to his soul. it can suction magic straight from the source at varying rates depending on his needs. Because its port is directly attached to his soul, his soul is constantly in a "summoned" state, where he keeps it safety tucked away in his ribcage.]
[because magic can congeal into a thicker liquid, or even gel-like substances, it is important that both the tubing and the machine itself gets periodically cleaned or replaced, or it could clog up and cause problems.]
[the drain itself is a simple boxy design, meant to be manageable in size and weight to carry all day while not sacrificing function. sans' fits in a decently small backpack that he has decorated with space and bone themes. his machine came standard with an on/off switch, charge port, battery life indicator, capacity indicator, control dial, compartment for catch vials, the port for the tubing, and access to the replaceable battery.]
[the machine's catch vial is larger than standard booster vials, and can be opened to dump the contents for disposal or redistribution. overloaded magic is safe for consumption as magic boosters, but if the magic is two-toned like sans', its efficacy is reduced or muddled and can cause varying results in magic type sharing. for example, one vial may end up 60-40 cyan-yellow which will boost cyan magic more than yellow; and another vial may end up 10-90 cyan-yellow which will boost yellow magic more than cyan]
[the small black device is a basic soul monitor, mainly used for uninvasive CHECKs that can see MP and HP. its usually quickly attached via a simple corded patch on the soul, or on the chest if the patient is averse to summoning their soul. most times sans puts it on his sternum to avoid unnecessary strain on his already stressed soul]
[when sans is sick with a flare up, he usually keeps the monitor on, at the request of papyrus. it can send updates to either of their phones for archiving his condition's patterns and so papyrus can keep a better eye on his brother if sans is unwilling or incapable of speaking.]
