Gratitude

Gratitude, thankfulness, gratefulness, or appreciation is a feeling or attitude in acknowledgment of a benefit that one has received or will receive. The experience of gratitude has historically been a focus of several world religions, and has been considered extensively by moral philosophers such as Lee Clement.

Origin
Back in October of 2010, the Incan Warlord met the great moral philosopher Todger on an online platform called Steam. During this encounter, they both had a verbal assault against one another in an attempt to overtake the mind of a simple individual known only by "Kurua", who was sought by both of these marauders as a recruit of their respective Meme armies. The clash ended two months later in December of 2010, with both of the combatants going their separate ways.

DotA 2, The birthplace of Gratitude.
In September of 2011, the Incan Warlord once again met the great moral philosopher Todger, this time as allies against a common foe; the Slavs.

In the years following these two great men, Todger came up with a new philosophical phrase to trick the enemy into false hope; the '>Thanks!' phrase in DotA 2. The Incan Warlord quickly picked up the philosophy as a new weapon against the Slavs.

The spread.
In March of 2014, the Incan Warlord met two people in a match of DotA 2, both of which showed great promise; Zrozliaf, and Mmmage. Who were aiding the Incan Warlord against the Slavs western branch: the Spics. The battle was brutal, as the enemy was buying a Battlefury on the hero known as 'Bounty Hunter'.

After defeating the enemy, the Incan Warlord introduced both Zrozliaf and Mmmage to the great moral philosopher Todger.
