Last night, I deleted my creature cache file so NPCScan would work, logged in, and flew twice around Sholazar. Expecting nothing.
Right as I was getting to the last spawn point for the second time, there he was! And now he is mine.
He’s named after a Twitter friend who suggested naming him “Mike”. (I named him, posted the picture, and then anxiety brain went “oh but what if he thinks that’s weird.” But he said it made him laugh, so it’s all ok.)
So it really is Beast Mastery forever now. Because after waiting so long to tame him, how can I ever put him away? I mean, other than to take out one of my other spirit beasts like the show off that I am.
