In this period i follow the translation of fallout equestria (in italian of course), because i think who that novel deserve a translation, but i have two doubts with two figurative senses (i think) and need help.

1) ”“We must throw the party! Our Goddess demands it!”

In the chapter 37, there is an crazy alicorn who arguing whit herself, and say this sentence. But what she mean? I don't think she want to make a party with baloon, music and cupcackes, but i'm not sure.
In the rpg videogames party is also used for the group of adventurers, maybe she want to leave the alicorn's group in canterlot because don't follow the goddess?

2) The alicorn was showing raider-tier obliviousness.

in the same chapter Littlepip sneak near the crazy alicorn, and she don't see her. That raider-tier mean the absence of raiders skill in the alicorn?

thanks for every help
