My logins..
Applecitron - I felt like having pie when making this account. Applepie. With a little bit of lemon (citrus) on it.
HedCker - From my FPS era. Head Seeker.
Wywernywin - I made a character called Meradang Wywernywin in Baldur's Gate, in the Wyvern area. Damn things were killing my party all the time, and I wanted to win them wyverns.
Yargniathus - Was hanging out at #Blackmetal_fi in QuakeNet, and I needed a blackmetalish twist on my name, Jani. So.. Ja -> Ya, little rgn fluff cause it sounds angry, ni stays as ni, and random name ending.
