Thanks for the kind offer.
I am currently trying to work something out with Dryzzid where we try and swap guildstones. Currently I think this would be the best home for it, and I'm going to try my best to make something happen. I'm not looking to leverage the stone or profit from its history, I just would like a fair trade like Nabin has said above. I would really love to have either an HTML guildstone, or one that originated from LS (my home shard) so I can keep something sentimental in my collection. As Dryzzid and I have already discussed, this process could take some time and potentially involve multiple parties. I'm also waiting to hear from other interested people who may have a strong claim to the stone. Will keep you all updated as we go along.
