Although it does not do a lot of changes, Excalibur | Demi's Sky Arena Support changes the few little items available to fit the Excalibur themes! To those who play with emissives be warned: I wasn't able to see them myself, I'm not sure why. Despite having the Continuity mod installed these emissives did not load anyway either in my resourcepack or the base mod. If you have any problems like me, I'm sorry, I will not be able to solve them. Yet for those of you who can see the emissives, I hope you enjoy them!
