Wait What's The Au You And Your Friend Made About Phillip?

Wait what's the au you and your friend made about Phillip?

If this isn’t making any sense it’s cuz i’m writing this at 1 am 

didn't expect people to actually be interested in it but alright

 so basically the collector is freed by philip and possesses luz's body since their old body was destroyed and his soul put in a piece of glass (he can still use all his magic while in luz's body since he doesn't need a bile sac to use magic)

 and on the other hand you have belos who after capturing the curse in his mind instantly regrets it cuz the curse, yes made him age quicker, but also prevented him from dying of old age. so a bit of an oopsie cuz he got rid of the only thing keeping him from dying of old age so his health is rapidly declining

 so he decides to go to the collector and asks him to make him younger but after being trapped in a piece of glass the collector is a bit rusty at doing magic (but he just completely ignores that fact and just thinks 'yeah what's the worst that could happen')

 so he obviously fucks up and accidentally makes philip like 10 again leaving him confused as hell as to where he is since he forgot everything. the collector decides to use this to his advantage since now they have a gullible witch hating kid to help them cause as much chaos. 

also the reason why philip doesn't hate the collector for being a demon from a realm full of witches is because the collector lied to him about being a human (since he is in luz's body) who got cursed by a witch and that's why he's blue and yellow. philip ofc believes him being a literal 10 year old that got pulled out of the 16th (not literally just mentally)
