CultofKarasuno
Lance loved his friends. They were like his family, irreplaceable and comforting, and Lance made sure they knew it. 
However, after a run-in with a Druid, Lance has started acting... different.
He's rude, blunt, paranoid, and, with no other way to put it, cruel.
Desperate to figure out what's possessed their friend, the paladins realize; Lance has become trapped within his own mind.
And, ever so slowly, they're losing him to himself.
