It may be of interest to those of you who play pen-and-paper RPGs, that the Keltia roleplaying game is now available in PDF format. Set in 485 AD, it is an Arthurian game very firmly premised upon the myths and legends of Cymru, rather than the knights in shining armour of Mallory. There is plenty of Welsh in the game too; as a flavour:
The two principal mountain chains are the Eryri Mountains peaking at 3560 ft, which occupy most of Cymru, and Hen Ogledd’s Highlands (4035 ft). The Eryri Mountains include the Yr Wyddfa (“the tumulus”), home of Rhitta Gwar, the red giant, and door to the Annwyn.
The game posits that “Arthur” is the son of Einion (Yrth) ap Cunedda, Gwynedd’s Pendraeg and Emrys Wledig’s daughter. Players take on the role of clan warriors, sword brothers, bards, druids and mages adventuring in dark age Ynys Prydein, a world full of magic, mystery and epic quests. I’m still working my way through the rulebook, but it looks tasty.
