From publisher blurb:
A caravan of travelling priests murdered.
The bones of a long-dead saint stolen, claimed by barbarian marauders.
A monk desperate to see the ancient relics safely returned.
What’s so significant about a box of old bones?
The idea behind Parallel Adventures is that they can be slotted into most fantasy settings with little effort. The gamemaster should take the time to read through the adventure and decide on what changes are necessary to make it fit into their world. So, whether you are running a home-brew setting, Gloranth, or Forgotten Realms, the Parallel Adventure can slot right in.
As well as being setting-agnostic, parallel adventures are also systems-agnostic, and comes without any stat blocks. Depending on the power level of your player characters and your preferred system — be it Dungeon & Dragons 5e, Pathfinder or Savage Worlds — this is where you will have to do the most work. Prominent non-player characters feature a brief description that should serve as a guide to their capabilities, but you will have to do the rest.
