Blacksmith and Thieve's Guild. The blacksmith makes sense as is a very low-tech form of modelling the Iron.So good choice for Modoc. A foundry would be too advanced.Someone said from where people of Modoc would learn about blacksmithing. LEt me think, let me think...Vault City, being close, I'd say that would be a source of pre-war knowledge.Maybe some disgruntled citizens moved in and formed Modoc a long time ago and than some others came on the way. Perfect logical answer. Also let's not forget that there are many enclaves that are keeping alive the science and the technology, enclaves like Brotherhood of Steel or the Enclave, The Shi and the Hubologists, Vault City also...And the Brotherhood spreads the technology wherever they can get some raw recruits. So take your pick from where a small community like Modoc would get her tech. The Thieve's Guild should have been in some other town, but for a covert HQ, Modoc wouldn't be ideal. Let me explain why: small community, any newcomer attracts a lot of undesired attention. For a Thieve's Guild, anonimity it's a must. That's something that Modoc can not offer. A big city like San Francisco or New Reno would be the ideal for that. The mod idea is great, just needed a bit more background and to be shown the weakness of a Thieve's Guild with an HQ in Modoc. Hope you will relocate that somewhere else, otherwise the idea it's great.
