I have the Clockwork and Steam pdf, but haven't read it yet.

I didn't realise there was so much background information in it.

A few more observations that I made when compiling this timeline:

Dwarves:
The Dwarves of Blackmoor are hard pressed. 6 wars with the Orcs have taken a heavy toll on the dwarf population and conflicts with Thonians etc hasnt helped either. Both Oberstar and Lortz have been loyal supporters of Uther and will be dependent on getting something back from that relationship soon. However, Uther seems occupied elsewhere.


Gnomes:
Gnomes are a fairly new race to the North, having only been in the region for 200 years. I connected their arrival with Mieroc's ascencion to Immortality. So Blackmoor Gnomes would be a sort of pilgrim folk. This contrasts to other descriptions of them in the DAB sourcebook as gypsy-like travellers.


Oh, and not sure if anyone noticed but the detail about the first Titanium Steed being lost in the Blackmoor Dungeon was something I added because I want that to be the horse used by the Blue Rider. I omitted another reference from C&S about the horse being made by a Cumasti elf. Elves should have no business playing around with steam tech IMO...
