Eitr is a scarlet-colored metal with a symbol U and 124 protons. While lying in the island of stability, with a half-life varying between 100,000 and five billion years. Eitr is remarkably dense, nearly as dense as Osmium, and thus shares many of the same applications. Eitr is a part of the Mythrides, the group of elements in which electrons begin to fill the g-block. Most of the elements of the g-block are radioactive, but have much longer half-lives than the previous elements.

In terms of jewelry, Eitr ranks amongst the most sought after commodities. Despite its radioactivity, collectors, royalty, and the ultra-wealthy throughout the universe. Some trade their health for the status of wearing the striking metal. While too dim to see in most applications, coating with a thin layer of phosphor amplifies its color, making its color much brighter than otherwise possible. Some have even gone so far as to augment their body with the metal, even eyes in extreme cases, to show off their wealth. With enough supplementary healthcare, its mild radiation can be overcome.

Applications

Eitr, while widely praised for its aesthetic properties, also has valuable applications. Eitr Oxide, similar in structure to corundum (aluminum oxide), is used in LASER dissipation, consequentially also making it a good focus for LASER weaponry. While sometimes used in specialized shielding for infantry or security use, it is more widely used on smaller spacecraft. Satellites, missiles, and even expensive slugs can be coated in the material to protect against point defense systems.

As a pure metal, Eitr has found applications in specialized displays. When used for this purpose, the resulting display has an iconic scarlet coloration from the individual atoms embedded within. While not so much used in hand-held devices like Scrolls, its use to produce vibrant eye-catching signs or displays is quite common.
