Interdimensional trade is no simple matter, just using the teleportation gate of the Tower of Truth is enough to pose numerous challenges.
The multi-world giant teleportation gate of the Tower of Truth is the only teleportation gate that most of the Wizard Commerce can use for interdimensional trade.
Because maintaining a teleportation gate is an immense expense for most Wizard Commerce, and transferring the teleportation target is an exclusive technology of the Tower of Truth.
If a Wizard Commerce established its own teleportation gate, they would need to dismantle it and reset the world coordinates when they wanted to switch worlds.
That constituted a significant expense.
After nearly two months of waiting, it was finally Nine Star Chamber of Commerce's turn to use the teleportation gate.
