Rune Stones are one of Ultima Online's most useful items: When used as the target of the Mark spell, the caster's current location is stored within. Anyone with access to the rune may then travel there instantly using the Recall, Gate Travel, or Sacred Journey spells. They may be purchased from NPC Mage Vendors.
Runes weigh one stone each and cannot be stacked. However, once marked they may be placed within a Runebook. The books also weigh a single stone but do not gain weight no matter how many runes are placed within, and can furthermore be used to store Recall scrolls for those characters without magical capabilities of their own.
Once marked, a rune will change color according to the Facet it now leads to (though they can be personalised using a Runebook Dye Tub). In addition, it will be named according to the area within that facet. You may rename runes by double clicking on them.

A rune marked in the Tokuno Islands.
A rune marked in Ter Mur.
It is also impossible to Mark/Recall while in one of the Feluccan dungeons. While it is possible to Recall around the Feluccan Lost Lands, you may only do so if you are already in that region, and may not use Recall to leave. You may not Recall to a tile occupied by another character.
