You could probably think outside the box on this one. Even look into some already existing items and consider them to have a connection.
For example Cape of the Montebank lets you Dimension Door one time per day. Considering your are talking about creatures native to the Astral Realm it is possible they may have developed this item to allow them to use its effect for quick travel on Prime Planes. Effectively bypassing space by utilizing Astral Space to travel through then back out. This item could, dimensionally speaking, connect two colored pools that access the same Prime Plane, and thus allowing its user to move through them in a moments amount of time.
