Backpack

Nothing is more embarrassing for an adventurer than to find the big treasure and then being unable to take the masses of coins with you. And it is downright lethal to go adventuring without carrying equipment with you.

For these situations, a backpack is very useful. Worn on the back it does not hinder the adventurer in any way, but allows transportation of numerous items without problem. It therefore is absolutely essential for every adventurer to have one, otherwise he or she shouldn't even bother with leaving town.

Backpacks were first available in Ultima VI, although during that time they were only extra space and not essential. However, starting with Ultima Underworld, having a backpack became essential, even more so in Ultima VII, Ultima Underworld II and Ultima VII Part Two. Starting from Ultima VIII it was a part of the interface and could no longer be un-equipped.

Trivia

 * In Ultima IX, Blackthorn takes away the Avatar's backpack at one time of the game. It is very annoying to not have it, and once the player gets it back, it has turned into a complete mess.
 * From Ultima VII onward, size and mass of an item were importat. This was only changed in Ultima IX.
