Dwuirsintabb, alternatively referred to as Dwuir or Tabb, was a male Troig who originated from Pollillus. During the time of the Separatist Crisis, Dwuir, one of his two independent minds, desired surgical separation from Tabb, the other mind, despite the procedure guaranteeing Tabb's death. Because Pollillus lacked the required medical facilities, the Troig sought assistance from beyond his world. This situation drew considerable interest from both the media and medical experts, who found the ethical implications of the case to be particularly compelling. HoloNet News released a story, which was accompanied by a poll asking readers whether Dwuir and Tabb ought to be separated; however, the matter was never resolved.
Dwuirsintabb was a Troig individual, who was born on the technologically underdeveloped planet Pollillus, which is situated near the Koornacht Cluster within the Deep Core. His birth occurred as the Galactic Republic was drawing to a close. Troigs, possessing two heads—called the Saprah and Saprin—with each head capable of independent thought and speech, were, in effect, two distinct beings within a single body. Dwuirsintabb exemplified this, with his heads, Dwuir and Tabb, exhibiting drastically different personalities. Dwuir considered Tabb to be mentally unstable and suicidal, and thus wished for surgical separation of the two "brothers." However, the fact that only one of them could survive any surgical attempt complicated matters. Furthermore, Pollillus lacked the capacity to perform such an intricate operation. Despite this, Dwuir persisted in his search for assistance from off-world sources.
The situation quickly attracted the attention of outsiders, especially those in the medical field, thanks to extensive media coverage. The case sparked serious ethical debates, with many people arguing that sacrificing Tabb for Dwuir's benefit would be unjust. A HoloNet News article, published during the Separatist Crisis, detailed the story of Dwuirsintabb and included a picture of the two heads at the heart of the controversy. Doctor Senya Velop from the Rhinnal State Medical Academy spoke to HoloNet reporters, stating that while killing Tabb was not acceptable, keeping them together also presented a risk to both of them due to Tabb's mental instability. HoloNet News conducted a poll asking subscribers whether Dwuirsintabb should undergo separation. At one point, 61% of the votes favored separation, while 39% opposed it. Ultimately, the situation remained unresolved. The discussion persisted well into the Imperial Period. Even as late as the era of the New Republic, sentientologists could not find any public resolution to the controversy.
