The Lone Wanderer's crew become famous either as suicidal slavers, or cleansers of th wasteland. Using sneak and stealth tactics, as well as mysterious pre-war technology, they were out enslaving every raider in the Capital Wastelands.
Regulators and Wastelanders that would normally condemn slavery turned a blind eye on the Lone Wander. No one could deny that the Lone Wanderer's actions were improving the wastelands. Turns out the people the Lone Wanderer had to watch out for the most were other Slavers.
Slavers saw the Lone Wanderer as a competitor and constantly tried to assassinate him. They only stopped after he offered to buy slaves from them for twice the price what Eulogy was offering. Soon, the Lone Wanderer became the number one slave buyer in the wastelands. People were selling slaves to him before selling to Eulogy. By using the caps he gained from raiding raider camps, his crew was able to buy any slave, any time, anywhere.
After Eulogy caught wind of what the Lone Wanderer was doing, he set out to stop him. Eulogy saw that he was getting less slaves then he could. Less slaves meant less profit.
The first thing Eulogy tried to do was hire Talon mercenaries to kill the Lone Wanderer. To his surprise, they refused. Turned out, the Lone Wanderer constantly hired Talon mercs to travel with him. Talon Company couldn't kill someone under their protection. Eulogy asked when the trend started, after he paid a large bribe, he found out it began after the Lone Wanderer paid them to take out Slavers at the Lincoln Memorial.
Eulogy then tried getting the regulators to kill the Lone Wander. He gave them forged slave receipts, showing that the Lone Wanderer was enslaving Children. The Lone Wanderer, however, was in good terms with the Regulators, they could all tell the receipts were fake. To further prove his own innocence, the Lone Wanderer had children from Little Lamplight vouch for him.
After failing twice, Eulogy returned to Paradise Falls and tried to get the slavers there to ambush the Lone Wanderer. To Eulogy's surprise again, they all refused. By this time, all the slavers at Paradise Falls were selling they're slaves to the Lone Wanderer.
Now realizing that the Lone Wanderer had everyone at the palm of his hands, Eulogy tried to outsource the Lone Wanderer in another method.
Eulogy began buying slaves from the Lone Wander for half the regular price, and offering to buy slaves from everyone else for double what the Lone Wanderer offered. The Lone Wanderer knew what Eulogy was doing, and decided to take a few days off from the slave trade.
Sure, the Lone Wanderer could've sold slaves directly to pitt slavers, but that would've only shifted the slave industry from one place to another. The Lone Wanderer knew that in order for slavery to end, Eulogy needed to fall.
Eulogy soon realized that the prices he made couldn't be kept. He bought slaves for too high, and couldn't sell them high enough to make ends meet. He wondered how the Lone Wanderer could've afford the prices he had placed. Turns out, the Lone Wanderer found a bottle-cap machine, he used it to buy and free slaves. The Lone Wanderer enslaved raiders to help people, not to get caps.
Slavers soon realized that Eulogy was a bad middle man. They began selling slaves directly to the pitt slavers. Eulogy fell deeper and deeper into debt. In his blind rage, Eulogy headed off to kill the Lone Wanderer by himself.
Eulogy tried to kill Lone Wanderer outside of Tenpenny Tower. When Eulogy drew his plasma pistol at the him, Charon, Jericho, and Clover, were ready to shoot him. The Lone Wanderer stopped them from firing. He instead offered Eulogy a deal. He offered to pay off Eulogy's debt, as well as to buy paradise falls from him. Eulogy, deeply in debt with no allies left, was forced to agreed. After the deal was made, Eulogy disappeared. Although no one is certain where Eulogy is today, there have been reports of him working in the pitt as a slave.
