For anybody who wants to join in on my Pendragon events but doesn't own the rules, don't feel intimidated - Bundle of Holding has you covered! They have the 5.2 edition of the rules plus a number of sourcebooks up on Bundle of Holding here: https://bundleofholding.com/presents/KAP2018;
and also here: https://bundleofholding.com/presents/ArthurianLands
The differences between Pendragon editions are not very significant and sourcebooks and adventures can be used pretty much with any edition and very minor tweaking. So, then, let us win glory for our King, who will reward us with honors and lands, and the devil take the hindermost!
