Hello again! I do hope making multiple requests is acceptable, separately of course. And I just wanted to thank you in advance for accepting my last request, I'm glad you saw it fit to add. 
Now, this mod I'll go a little more in depth with the explanation. Although it's been quite some time since it's last update, the last version being for MC 1.7.10 I believe, they've recently released an alpha build for MC 1.8.9. Firstly let me say that this Mod is an extremely unique one, similar to my last request, although a vastly different theme of gameplay. I'm sure some have played this mod, however seeing how long it's been without updates, I can understand if it has lost its popularity. However if you haven't played it before, I urge you to set aside an hour of spare time and check it out. It won't disappoint!

What is so unique about this Mod, is the fact that there is amazingly put together custom content that can be added in, however if this would be a problem considering the way the Aternos Servers work, even the standard Mod is enough to satisfy. This is a link to the Custom Content, I just want to be as detailed and thorough as possible to make it easier on your guys' end.

Waiting for the alpha build to become stable would probably be the best bet, as I haven't personally tested it yet, although in the meantime I think the 1.7.10 version would work nice! Let me apologize again in advance if this has already been requested, and if it has I hope this gives a tad bit more insight into how truly great of a mod it is ! Thanks for taking the time to read this Aternos team, you're the best!
