As it is St Patrick's Day on your plane of existence, I thought it timely to warn you about the Leprechauns of Titan.
As any adventurer in the lands of Allansia, Khul and the Old World will tell you, Leprechauns are tricky and capricious individuals and so you should always be on your guard in the presence of one of these diminutive followers of Logaan the Trickster.
Remember O'Seamus in The Citadel of Chaos?
Or these fellows from Deathtrap Dungeon?
Or Muldoon from Shaggradd's Hives of Peril (as related in Fighting Fantasy - The Introductory Role-Playing Game) or even Finnegan O'Dinnegan from The Riddling Reaver?
Whilst not being intrinsically evil themselves, it is not unknown for them to lead unwary travellers into potentially perilous situations for nothing more than their own amusement.
So take care this St Patrick's Day evening, Leprechauns are particularly likely to have their fun with brave adventurers who have maybe had one too many flagons of Cloud Ale, and if you do end up in a horse's drinking trough with your breeches round your ankles, don't say I didn't warn you...
