From the Age of Splatbooks: Charlemagne’s Paladins by Ken Rolston and Roger Raupp
Charlemagne’s Paladins (TSR, July 1, 1992)
One of the more interesting developments during the AD&D Second Edition years (1989-2000) was the Historical Reference series of campaign sourcebooks.
These green “splatbooks” were well-researched, taking a broad view of history, myth, and legend, and looking at all of it through a D&D lens. Charlemagne’s Paladins is one such shining example. Written by Ken Rolston, illustrated by Roger Raupp, and with cartography by Gaye O’Keefe, this sourcebook adapts the historical setting of the Carolingian period into a quasi-game world, featuring the historical and legendary personalities and events of Charlemagne’s time.
