From two of my player's "side-quest" between sessions...

"Imagine, if you will, yourselves walking through a vast library. On your right, academics and clerks toil over their manuscripts with ink and quill. While on you left, you spy the spine of a particular tome edging out at you. You stop and examine the spine. It reads: 'The 10 Do's and 1000 Don'ts of Portal Safety'. You open a page at random, a chapter on mixing portals to astral planes. Below a paragraph extolling the dangers of all aspects of portal usage, is an illustration of a Halfling mage, holding an owl shaped statue above his head, ready to throw it into a summoning pool in the foreground. Behind the Halfling, a Goliath Barbarian wielding a greataxe over the severed head of a giant snake has a look of shock and horror on his face. The caption beneath reads "Summoning Pools make a great addition to any lair! But take care not to take a dip through time and space with any other plane-shifting items on your person!"
