Essence of theUr-Dragon

Contained within this Crystal vial is a liquid of shifting darkness, in which sparks of light can be seen and someone the distant sound of a dragon's roar can be heard. Upon drinking this vial, you are imbued with all the power and might of the Ur-Dragon, who travels betwixt the planes within the Blind Eternities, descending only briefly onto planes to spread the blood of dragons to them.

• You have access to all five colors of magic, able to wield any of them with a strength that terrifies any mortal who sees it, shaping the raw mana to your will and bending the Plane to your obviously superior will.

• When you descend onto a plane in what all who see it will describe as "A shadow upon the world", and flap your wings, you'll generate Dragon storms, from which Dragon eggs of every color will spawn. From those eggs will be born Elder Dragons, the strongest of your children, but still a pale shadow of your magnificence.

• With a mighty roar, you can call upon all Dragons who can trace their origins back to you, no matter how far back that origin might be. This call will emanate across worlds, granting all who hear it the ability to travel to your side and aid you in whatever manner you require.

• Of course, as the gratest and mightiest of Dragons, you aren't limited to merely existing in your glorious dragon form. You can manifest a lesser form, an Avatar which can enter a plane without calling forth a Dragon Storm or letting others know of your presence there. This Avatar can take on any appearance you wish, and be imbued with any combination of Color affinity for magic. On top of your ability for magic with the Avatar, your physical traits are far beyond most mortal species, leading most to either assume you aren't as you appear or are using magic to boost your abilities.

• Much like the Eldrazi, you can exist in the place between worlds without harm.
