The White Hounds

An Uncourteous Hunt
The encounter
While hunting in Glyn Cuch, Pwyll sees Arawn’s white hounds bring down a stag. He drives them away and sets his own dogs on the prey.
The consequence
Arawn identifies the act as a grave failure of courtesy. Pwyll’s first challenge is not battle but accepting responsibility for an offense he did not understand.
A Year’s Exchange

The Kings Exchange Places
A bargain
Arawn offers Pwyll a year in Annwvyn, with Arawn’s appearance and a queen as his companion. In return, Pwyll must defeat Arawn’s rival Havgan.
A test of trust
Arawn will rule Dyved in Pwyll’s likeness, trusting that the substitution will not be discovered. Their pact makes mutual confidence the condition of political success.
Rule in Annwvyn

Pwyll Learns Another Court
A borrowed kingship
Pwyll enters Arawn’s court and is received as its ruler. He shares the Queen’s company but respects the boundary Arawn has set between companionship and intimacy.
A measure of character
The year is filled with hunting, feasting, and courtly conversation. Pwyll’s conduct shows that wearing another king’s likeness also means bearing his responsibilities.
The One-B Blow

Havgan’s Defeat
The decisive strike
At the ford, Pwyll in Arawn’s form strikes Havgan down. Havgan asks for a second blow, but Pwyll refuses, following Arawn’s specific warning.
Victory without excess
The choice ends the contest while preventing the defeated king from recovering. Pwyll’s restraint completes the task as carefully as his courage began it.
The Friendship Sealed

Recognition and Reward
Restored identities
Pwyll and Arawn meet again and resume their own appearances. Each has kept the other’s kingdom safe, and Pwyll has united Annwvyn’s rival territories under Arawn’s rule.
A lasting alliance
Their reciprocal gifts and continued friendship transform a dispute over etiquette into dependable political fellowship. Pwyll thereafter bears the honorific Chief of Annwvyn.
