D&D4 Aventuria: Sacrileges are fun

I decided just to kitchensink everything D&D4 has to offer (including the unaltered rule system) into the Dark Eye campaing setting of Aventuria. This will create lots of fun: normally Aventuria has no halflings for example. I will just decide that the travelling (human) merchants there - the Norbarden - were cursed into this smaller form centuries ago.

First thing to do, is to contextualise the low level encounters from the Monster Manual for Aventuria.
