Ok so the BLL in this blog was just a normal DLL in Five pebbles. They..I guess "formed" during the monk-rivulet timeframe. Specifically in One of the big memory conflux rooms. (Probably RM_D02.) The reason they have all this.. Information is well... Because they got lucky. How do they know that rivulet stole the cell and caused five pebbles to fall? They just...say them. After pebbles collapsed and became silent construct. They wandered around.. Freezing..slowly dying... Then they went through a random pipe while chasing a cyan lizard and ended up at..pharloom. How? Idk. What do they want? A lot of things..
(Most of this lore is gonna be from other posts. This is just where Im putting all of it.)
1: BLL goes by they/it pronouns and has not felt any love (and does not.. Intend to.)
2: Most if not ALL of their knowledge of the world is from all the pearls/neuron flies they have ate.
3: if they got iterator like powers.. Uhh... It would not go well. [powers include: telekinesis, being able to shoot laser beams(like the ones in challenge 70.), Lighting manipulation(the lighting is the same as the lighting/sparks in the leg+underhang.), oh and uh gravity manipulation. That's it :]
4: The reason they have sentient rot abilities is because...uhh..idk. Probably ate some void fluid or something.
5: caused the putrified ducts to become the infected ducts
6: they are still weak to explosives. BUT can technically come back after death. (Only if their neuron flies are intact.)
8: eating rot/things made of rot taste like.. Moldy lead. I guess. And the symptoms are: hallucinations, nausea, vomiting, lowered sense of self preservation, small tumor like growths of rot on your skin, and worse vision and hearing.
9: they're able to put information on a pearl. (Or something like a rosary would work too.) By uhh... Idk they consume it and then when they get the pearl back it has.. Information on it. (This is when their NOT in their iterator form btw.)
10: they CAN see and hear. How? Uhh.... Idk...uhhh.. I honestly have no canon explanation for it. Uhhh... I.. Have literally no idea. Probably the same reason they now have.. Sentient rot.. Powers?? Idk.
11: the BLL is 12ft tall casually (when its not doing anything.. Important.) AND 16ft at its tallest! (fully stretched out tentacles.)
12: The BLL is a mental mess. Uhh.. 10 neuron flies, all being slightly different. Also with very old memories from pebbles affecting it as well.
Will update this list if needed :)
