Good! The place can be repaired. I just made a Tale of Kingdoms world, and the same thing happened to me. On, I dunno, my second night I hired a hunter and went out to kill a bunch of monsters. After a little bit, the guild master came and told me they'd been attacked, blah blah. The point is, it got set on fire, and I was wondering what I would do. But it can be repaired... yeah. That entire story was pointless, wasn't it.

Hey Guys! I have a Gaming network, I dont get many views nor do I have lots of Subs. It would be really nice if you guys check out my channel, comment and Subscribe.
That just happened to me now, my guild hall was attacked by reficules and was getting nothing but lag, and also lost most of my stuff cause most of my stuff where in one of the rooms on the top floor & when I got the stuff from a large chest I got killed by a reficule & most of the stuff went in a fire.
I lost a lot of iron as well, not all, but a lot. :-(
Hey martyn... could me and you and my friend do a custom map together... The channel is DarkEpicNinjaCraft... Just being curious.. Really appriciate it if we could do it together and sorry if I'm bugging you
OBJECTIVE! Stairway to heaven: ( :3 ) Build a stairway/tower all the way to the sky limit and build a ground out of 20x20 wooden blocks and spawn in a ghast egg and spawn 1 fight and kill a it (Any weapons can be used, Don't die :L and adding to the platform is allowed :3) GOOD LUCK :D
Hi Guys, I know i'm hardly one of the biggest names on youtube, but I was hoping that could change. I regularly upload minecraft vids (A new addition is HD format!) And I need your help(I know you guys are awesome because you're watching this vid) So please take a few minutes to just check out my vids leave some feedback and subscribe if you like what you see. I really appreciate every new subscriber. Thanks. :-)
One day when Martyn was fighting Reficules his freind Xephos called and said that he had a run in with Israphel and the reficules. He told martyn that a guild over by the forrest of littlewood was under attack by strange creatures, It is up to You martyn to save the World of minecraftia from the reficles and drive israphel back into the sand!
I'm actually kind of missing the old kingdom, and I didn't really like the way he just started us off in the middle of everything and didnt start explaining all about the yogbox until half way through the video.
I un-subbed and stopped watching your videos after you decided to make up your own questline on a lets play of an already set out questline. Sorry, bye.
I was sad at first but then when you said that you where using the YOGBOX I was so exited I nearly jumped when I'm on my bed that less then a foot from the ceiling!
GOAL: Make a overwatch house over your new kingdom then at night you can become super martyn and kill mobs and have a sidekick dog! BYEEEEEEEEEEEEEEEE
