These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Ass Pull: Heitz is prone to this. A lot. for instance, in the third book Tungdil and Lot-Ionan are both killed and almost instantly resurrected as if death is just a minor inconvenience. The Author is a cheating bastard indeed.
Inferred Holocaust: the genocide of orcs and Alfar is only hinted at: one half-Alfar magic-user is seen to die screaming horribly, wreathed in fire. Expeditions to the orc and alfar kingdoms find only bones and ash, all that remains.
Nightmare Fuel: The alfs, in all the books. They paint with blood, for goodness' sake!
