I play some Renpy game and accidentally press enter while giving MC name and found out that there is a default MC name. So I try with another game like Tavern of Spears and know that Eyvind is the name of the handsome wolf MC.
I knew about TOS having a default name since I believe it has in faint text "default name is Eyvind" when customizing his stats and naming him. it's still neat though :)
