In Ultima Online, the Runebook is a versatile and essential item for players who frequently travel across the game's expansive world. It acts as a container for up to 16 marked runes, which are linked to specific locations. The Runebook allows players to teleport to these locations using the Recall or Gate Travel spells, or the Chivalry skill Sacred Journey, without needing to carry multiple individual runes.

Each Runebook can be charged with Recall scrolls, enabling travel even without the Magery skill, and can hold up to 20 charges, depending on the scribe's skill level who crafted it. Additionally, players can personalize their Runebooks by naming them, dyeing their covers, and setting a default location for quick access. This item is especially valuable for reducing the need to carry multiple runes and ensuring swift travel across the game world.
