Elosha was a Colonial priest present at the decommissioning ceremonies for Galactica, and later presides over services within the Fleet.
Biography
The Fleet
During the Cylon attack, Elosha was on board Colonial Heavy 798, along with other attendees of Galactica's decommissioning. When the news of President of the Twelve Colonies Richard Adar and his entire cabinet being wiped out by the Cylons reached them, Elosha administered the oath of office of President to Secretary of Education Laura Roslin.
Later, after the Fleet's escape from the Cylons at Ragnar Anchorage, Elosha presided over the funeral service aboard Galactica for the ship's dead. With the crew suffering from shock and low morale, Commander William Adama sought Elosha's knowledge of the Sacred Scrolls and the legend of Earth to give his people hope. Elosha also presided over the Service for the Dead for the seven Galactica pilots lost in a freak accident during a celebration in the port hangar deck.
However, Elosha secretly had a crisis of faith. Although she was well-versed in the Sacred Scrolls and the history of the Thirteen Tribes of Kobol, she did not entirely believe in the truth of either. Her faith was renewed when she learned that President Roslin was having visions that mirrored the writings of Pythia, an ancient oracle. Elosha became Roslin's confidante and spiritual advisor and helped her discern the meanings of her visions.
She was the fourth person to learn about Roslin's terminal cancer, confirming in her eyes Roslin's role as "the dying leader" in prophecy. When Roslin escaped from incarceration on Galactica following her arrest in a military coup, Elosha accompanied her on a Raptor piloted by Lee Adama to the Astral Queen. She was visibly uncomfortable when Roslin decided to play "the religious card" to persuade 24 ships of the Fleet to follow her to Kobol.
While exploring Kobol, Elosha mentioned that the Scrolls warned that Zeus would exact a price in blood for any return to Kobol. However, she triggered an antipersonnel landmine left by Cylon Centurions while examining an ancient gravestone marker on the path towards the Gates of Hera and the Tomb of Athena and was killed instantly. Roslin took Elosha's copy of the Sacred Scrolls and continued her journey sadly without her.
In Roslin's visions
Two years later, Roslin experiences visions featuring Elosha during the Cylon rebel basestar's pursuit of the Resurrection Hub. With each FTL jump, Elosha guides her through an empty Galactica and shows Roslin her own death from cancer. Through these visions, Elosha tries to teach Roslin the importance of love and convinces her to save Gaius Baltar who is seriously wounded during the battle. Elosha also helps Roslin realize that Galactica is her home now and acknowledges her feelings towards William Adama.
