A/N: I'm not on fanfiction very often these days, but this idea came to me and it was too good to pass up. I'm planning to write a HDM/PJO crossover and this is some background material and the character's daemons. If the actual story is up at this point in time (at the time of upload, it is not) beware of spoilers.
Disclaimer: Percy Jackson and the Olympians/Heroes of Olympus belongs to Riordan. His Dark Materials belongs to Philip Pullman. I own neither.
Percy
Areti
It was probably the worst timing for Areti to settle, in the midst of the demigod's fight for Manhattan, but so be it. She had dived at a monster, clawing its back with her eagle talons, only to twist and fall to the floor, her body in a rat-like shape that Percy didn't recognise. An odd feeling settled around him as he swung his sword, beheading the monster and allowing his daemon to bound over to him and climb to sit on his shoulder.
"So, uh, what…?" Percy asked, spearing another monster that approached them and focusing mainly on his daemon.
"Some sort of possum, I should think," she replied. "We should ask Annabeth when this is over- hey, watch out!"
And they did ask Annabeth, hours later when the dust had settled and it was finished at long, long last.
"Definitely some sort of opossum," she told them. Then she laughed, punching his arm gently. "Took you long enough!" Percy laughed and reached up to stroke Areti's soft fur.
Areti is a lutrine opossum.
