2.6 Founding Towns
How are Towns founded?
A Town is automatically founded when at least four of your Structures with a combined Power value of 7 are directly adjacent to each other. If one of the Structures is a Sanctuary, only three Structures are needed, but still a combined Power value of 7. However, the Favor tile "2 Fire" lowers the Power value requirement to 6. Taking this tile might mean that one or several Towns immediately are founded.

2.10 Timing (getting Favor tiles, founding Towns)
The "2 Fire" Favor tile means that to found a Town I need Structures with a combined Power value of only 6. If I'm on 8 on the Fire Cult track and don't have a key, can I take this Favor tile and at once found a Town and use that key (Town tile) to advance to 10 with the 2 Fire influence from the tile?
Yes, if a Town would be founded by taking this tile, you get the key immediately, and may use it to reach 10 on the Fire Cult with the 2 Fire influence. (source)
