Wreaths

Full Item Description
How do The Grinches get here? Wreaths. These are not your normal green wreath hanging from doors and walls. The Wreaths of The Grinches are metal rings ranging from 1.5 to 2.5 meters (5" to 8") in diameter. The Wreaths are made up of wire bundles. The wires are a mix of silver, gold, and a metallic green. (The green metal is known as Yuelium, with such unique properties that it will become a strategic material). The bundles of wire occassionally have odd little geometic shapes the wire. They seem like little ivy leaves and odd shaped blobs of berries.

This all struck The Elfs as a Christmas Wreath. The Humans picked it up and now the name has stuck.

Wreaths just seem to appear. The Grinches' Masters seem to send them through The Void to this world. They just appear, power up, and open up the gateways. The Elfs quickly developed detecting globes to spot incomming wreaths. The Grinches responded by "planting" wreaths. These Wreaths start as 2-5 CM rings and grow into full size. They are placed and eventually activate. (Such wreath rings have been discovered a few times, usually just before they were activated). These rings and Grinches can be detected by certain toys the Elves develop.

The existance is Wreath Rings is disturbing. It means The Grinches (and their Masters) have been on Earth Realm for a while and have a greater plan. Another disturbing implication is that they have allies that are native to Earth (and a stockpile of Wreath Rings and Yulium items).

History
Humanity's and Elfkinds's experience started with Wreaths started December 24th at sunset in London.

One of the first Elf Assault Teams (or was it an Elf Rescue Team... the two divisions have a rivalry and both claim many firsts) first discovered The Wreath and watched it self destruct (and stopped the reinforcements comming through). Now part of every Elf Team starts looking for the Wreath to stop the Grinch reinforcements.

Magic/Cursed Properties
The Wreaths open a portal between the Earth Sphere and the Realm of the Grinches' Masters (aka The Dark Heart's). This portal seems to be two way. Otherwise, there would be no reason for the Masters to destroy Wreaths when they might be captured by Elfs or Humans.

When self destructing, The Wreath turns white hot and the gold and silver vaperizes. Some bits of Yulium survive and can help to make some awewsome technology and eTec devices. Note, a fire usually results due to the self distruct.
