Log storage chests are found around Mort'ton and may be used to store pyre logs for the Shades of Mort'ton minigame. They are only available once the medium Morytania achievement diary has been completed. They may store up to 30,000 of any type of pyre log, and these may be taken out at any time, but only one type can be stored at a time. Logs can be stored in noted form, but not taken out as such.
Mort'ton contains multiple chests, although they all use the same storage bank. One is found by the funeral pyres at the western border of the town, another in the south-western corner, another in the south-east and another just by the bridge towards temple Flamtaer.
