An explicitly F2U Arden: Some Arden animations I made - #2 by Marymory
Obsidian Daddy made some older mugs, they were probably intended to be F2U. You should reach out to clarify, he’s very active on FEUCord and just earlier this month gave his blessing for someone to finally script his old Mage Fighter animation.

On the subject of Salem, turns out that Salem portrait that’s in Burger King and Blademaster’s WIP FE5 remake is credited to “Redfe” which isn’t a person, but a 2017 hack, where the portrait also appeared. In the Redfe thread is confirmed to be made by Bluey[guy]. I think it’s probably O.K. to use that Salem mug?
