I'm about half way through Will Wight's Crimson Vault, Traveller's Gate 2. It's a pretty fun book, not the best I've read, but I really like his magic system; the "Travellers" can open gates to other worlds/dimensions and use things from inside, like calling fire from Naraka or golems from Ornheim. The two main characters have special Territories; one is Elysia, The City of Light, which is supposed to embody the virtues of Man. The other is Valinhall, which is "artificial" according to some other travellers, because it is not old, compared to the other ten Territories. Valinhall Travellers call up power into themselves, instead of using things or creatures, as the other Territories do. They make themselves fast, strong, give themselves hard skin or perfect focus or knowledge of combat. They have to face tests in different rooms of the House, each of which grants them either a power or access to deeper parts of the House, where they can find more powers. It's a really cool system.
