Here's a cool picture of Brother Warth. His image brings back memories of the Hindu wisdom god Ganesha from World Religions class. During the recent Blackest Night series many other color rings are uncovered all of which have their own emotion, corps, and oath (most of which also possess Hal Jordan for a certain amount of time) one of these rings is the Blue ring of Hope.
"In fearful day, in raging night,
With strong hearts full, our souls ignite,
When all seems lost in the War of Light,
Look to the stars-- For hope burns bright!"
The symbol for each ring is also different than the original Green Lantern. This Blue almost looks like it has a dove's wings on the sides. These Blue Lanterns (Saint Walker, Brother Hynn, Brother Warth...) are useless without the Will of a Green Lantern close by (Hope without Will is powerless). But, with the Blues the Will is super-charged, almost limitless.
These rings are probably my favorite, not only are they a shade of my favorite color, but it adds the significance of the Spiritual aspect to the Lantern world. As the members are Saints, peaceful, trusting people who look forward to the future.
The first Blue Lantern, Saint Walker, was chosen by an excommunicated member of the Guardians. He received his power by leading his race to believe that they would be alright even though their sun was dying. Through this, the sun was healed. Walker is also rumored to be appearing in the Justice League of America pretty soon.
These lanterns are noted for saying, "All will be well." Barry Allen, the Flash, was also an honorary member of the corps during the Blackest Night.
