The Ark is a Relic.
The information below has been culled from a post to a Journey of Moses group.
The ARK is a relic you will earn by working the story maps after Moses comes back down Mt Sinai, with the Ten commandments.
...in these maps you are collecting parts for the Ark; The Acacia wood to build it & gold pieces.
...once you complete those maps look in your BUILD Icon (hammer & chisel) then in your storage crate, place it in your camp....
This is a continuing relic; you will find other parts/pieces as story maps are opened & are worked..
In the meantime to complete part two of this relic these are the items you will be needing.
...the 25 gold pieces & 2 poles will be completed when you have done the last maps that came out Feb 15th, 2012
...which will give you the balance of gold pieces & poles for carrying the Ark.
Then you will have the Ark of the Covenant which will give you two Gems daily.
