These placed effects are inspired by the Moongates from the old Ultima game series. They were originally intended for use in Ultima based worlds but may be of interest to anyone else looking for a different kind of portal.

Here is a little ultima lore from MokahTGS describing the significance of the different colors:
Blue - These will transport one across the world. Moongates appear in places where moonstones are buried (traditionally, there are eight moongate locations near each of the major cities), and the destination of the travel is based on the phases of Trammel and Felucca, planet Britannia's moons. One moon determines when the moongate will be visible, while the other determines the target moongate. It should be noted that the behavior of blue moongates isn't consistent in games; For example, in Ultima VII, all moongates are constantly visible.
Red - Requires an Orb of the Moons. Only two Orbs are known to exist, one carried by Lord British and the other sent to the Avatar by the gargoyles. Activation allowed for travel to any destination, which was determined by where the Orb was used. These allow the traveller to travel across worlds, most notably between Earth and Britannia. A red moongate was also used to exile Lord Blackthorn to Serpent Isle at the end of Ultima V.
Silver - A rare form of moongate. It allows time travel. The Time Lord was able to create them and they were involved in the pursuit of Minax in Ultima II. It is also possible to create them with the Orb of the Moons, as done in Martian Dreams
Black - Black Gates allows travel through space and dimensions. They can be produced by electrically charging blackrock. These moongates were needed by Guardian in order to invade other worlds.

To Hellcow, whose Cobweb effects I used as an example to figure out how to package these.
To MokahTGS who encouraged me to get these on the vault, and for reminding me of the silver and black moongates.
