So i couldnt go to sleep last night so i just made a warframe concept?
A lake verula themed frame with the rainbow eels and all that good shit. Shes tends to the eels and fishes (dont search for fish tender thats not what i had in mind oops xd) and she has an eel as a type of an opera featherscarf-thing that sings to her to buff for different stats based on the spiral emotion. I dont know what her 1st ability could be tho. The 3rd (rainbow scales) grants immunity to 1 status effect based on current eel color (maybe for the whole squad). The 4th summons the spectral form of the rainbow eel and deals that rainbow of status effects to enemies.
Her design is still undecided between like a fisherman/diver and something about singing since Luscinia has such a bond with them and the frame could have been her apprentice/ the frame would just sing to them while caring for them.
The frame could be coupled to a game mode like the isleweaver when we defeat wally or get him out of duviri. So its like a festival but instead of for only thrax its for the liberation of duviri. Stealth, survival and defense missions, as well as puzzles would match her personality. Boss fight is a golden maw (souped up obv)
