Ok, I need to correct two things.
The remaining three bidders are not the only guilds who have expressed interest, nor did all of them have 30 million tria. The Adani Order and Roots of Vocation both had over 29.5 million tria, and at least half of the money for both guilds came from metallurgy. The CW pulled out of the bidding well before the 30 million mark, and the Bounty Hunters did not have a bidder present.
As to the bid placed by The Adani Order, yes, we had loans. No, not all of our money came from loans. Glaciusor and myself have been glued to the forges and mines since this auction announcement was placed, and the rest of the guild, as well as many close friends mined daily and quested to fund our bid. We also went through our storages and started liquidating GM items, weapons collections and various other things to raise tria. We had a lot of help, and couldn't have done it without the people who were kind enough to help us with mining, hammering and loans. We are extremely grateful for that, and even now are working towards repaying the loans off.
