The Settlers' Call Fund represented an initiative established by Orrin Gault with the purpose of uniting the moisture farmers in the vicinity of Dannar's Claim. Its function was to mobilize these farmers in opposition to the threat posed by the Tusken Raiders. The fund provided financial support for the armaments and transportation utilized by the Settler's Call group. In response to the call to arms, farmers who contributed to the cause emitted a sound mimicking that of a krayt dragon. Following an assault on Dannar's Claim orchestrated by Tuskens under the leadership of A'Yark, the fund facilitated a retaliatory strike, resulting in a decisive victory against the Tuskens during the Comet Run Day Battle.
