Lost All Items After Falling Into Void in The End (Elytra Disabled)

This was my first time visiting The End on this server, and unfortunately, I wasn’t aware that elytra flying is disabled there. While exploring, I tried to use my elytra, fell into the void, and lost all my gear and rank skins.
Here’s what I lost:

• Full enchanted Netherite armor set
  
• Elytra
  
• My rank skins 
  

I completely understand the rules now and will be more careful in the future, but I’d really appreciate it if the admins could help me recover my items — especially since it was an honest mistake and my first time in The End.
