Direction

The direction is always east to west and from Habar Gidir to Marehan. It is never Marehan going west to east towards Habar Gidir. You will never see Marehan building birkas (berked/water catchment) towards Bandiiraadley or Cadaado or Guriceel. You will also not see Marehan livestock or camels and goats being freed east of Bangeelle limits to graze. This is an environmental feature that explains both why it is never Marehan going east and why HG is always going west towards Marehan. Hawd grazing stops at Caabudwaaq metro limits. At the point of the highway, a totally new environment begins which is less advantageous for camel grazing. If the environmental features were less lopsided on this, you would find Marehan going east which would be an even deadier set of circumstances as this would be a dual instigation of conflict as opposed to only one side as it is now.
Family
In particular it is never really all of Habar Gidir, even all of the ones directly neighboring Marehan, who are all equally motivated in pushing or even "rushing" west, in fact even inexplicably senselessly one thinks. There are 3 lineages from Habar Gidir who have intermarried heavily with Marehan and even popular oral history of those lineages self-identify each one of their maternal origins being from Marehan. Caydiid 's lineage from Sacad or the Cilmi Wardheere of Rer Jalaf, Mahad Salaad's lineage of Reer Ayaanle within Cayr, and Qoorqoor's lineage of Reer Muuse of Saleebaan. Each of their clan's oral history featurea Marehan maternal origins and they have historically heavily married into Marehan. Many of their lower level units even have at one time or another "lived with" or have been "hosted" for an extended period of time or another with Marehan.
Abandonment
The story I relayed about the 1st accused does not surprise me. I said it is the history of the Somali people for a reason. I am paternally from Balanbale. It is the same thing with Rer Ayaanle and Marehan in Balanbale as it is with the Rer Muuse of Saleebaan in this act and Wagardhac. In fact, the most unyielding, almost psychologically frenzied push no matter how rationally improbable is always emanating from the Rer Ayanle or the Rer Muuse or the Cilmi Wardheere who is the most recently most intimately related to Marehan---the one with the most recent history or memories of free access to Marehan, free privilege to Marehan grazing, protection status as binding as a Marehan walking among Marehan.
My mother's 2nd cousin on that warrant had a father and a grandfather, who were both sons of and husbands of Wagardhac, who, at a different era before things really fell apart, had the privilege to graze Qoolaaley and Qorof and Dacdheer and even Maganlo let alone Labagale and Bali Cad and even Dhabad----and he has never been able to step foot on parts (if not the biggest part) of his heritage the past 40+ years.
He has been fighting all his life to "regain" what he feels was "lost" to him.
I do not imagine, at all, that this was his first participation in blood spilling between Saleebaan and Wagardhac.
