If you do not play Towny and don't intend on exploring the End, this doesn't apply to you.
I accidentally jumped off an end city without wearing my elytra, and of course, with my incredible luck, I died. I have no clue where the items could be, but I also left my white shulker box with all my valuables on the nearby end ship. If someone can somehow retrieve the items, I'll reward you with 10k (my whole balance) and a few elytras or dragon heads if you want them. Please, please, PLEASE return the items if you find them. It's all I have on Towny, and it would be even more disappointing if someone found them and didn't return them to me.
Thanks much, see you on the other side... (of the End)
