I never quite liked the original blog's name to begin with (A Ludophile's D&D Corner) so it was always a tentative title until I found a better one. The new title is about an old story I heard about a group of AD&D characters who were exploring some nasty, old ruins, and they had, not surprisingly, a paladin among them.
The details are very vague but at one point the paladin died fighting a monster or by a trap. Since the character was loaded with too much treasure for anyone else to carry, and the group did not want to leave the treasure and the paladin behind, they were faced with a dilemma. Someone jokingly suggested that they put the paladin inside their bag of holding so they could manage to transport all that weight. It was never intended to be taken seriously but the idea of a dead paladin inside a bag of holding with his feet sticking out was memorable enough that the story became a private joke: whenever anyone needs a paladin, just open the bag of holding.
I felt this title was catchy enough for this blog. So, new title, same blog.
