Private Ragnar "Overkill" Otkellsson is a Tanker in Downfall Company, under the command of Corporal Frane Harth.
Otkellsson is a member of the company's One-Four Bravo fire team, along with Biran Gorgovic, Jide Mokus, and Shinji Kuronaga. Although he gets on perfectly well with his team mates, he has a preference for working with fire team Alpha's Bear Mtenga.
During the Second Liberation of Mibes, Otkellsson encountered Rendir Throam after a street battle against Viskr commandos, skulkers, and a blitzer. Otkellsson took an interest in Throam's obvious bodybuilding background, enquiring about his capabilities and choice of performance enhancing drugs. It was obvious that Throam's answers were unimpressive to him, and Otkellsson gave Throam a packet of white thunder to try. It was likely the influence of this blend of drugs which allowed Throam to later assault Euryce Eilentes (→LOTD).
Otkellsson was one of the Tankers assigned to Operation Keystone. On 23rd March 3745 ELC, on Guathelia, he and Bear Mtenga tore through a unit of Rasas just prior to locating Junn Delanka. He also took part in the battle for the grounding splinters, which were the objective of that mission (→TRD).
Otkellsson participated in the liberation of Forge Ruinous from an occupying force, as well as the invasion of the city of Arroch on Palanda Ire. He was also a member of the strike team sent to the surface during the Siege of Damastion (→FSS).
Shortly after returning to Night's Shadow from Forge Ruinous, Otkellsson was confronted by Euryce Eilentes over the drugs he supplied to Rendir Throam. During that conversation he told Eilentes that the narcotic usually brings out what is in people already, and implied that Throam was more of a sexual animal than she had realised. He roundly denied responsibility for Throam's actions, and suggested that Throam had had an insecurity relating to his size (→FSS).
