The Elephant
Okigbo devotes some words to his praise of the Elephant, specifically in "Hurrah for Thunder." He uses metonymy to describe the growing extinction of the elephant species in Africa. Once the majestic ruler of the jungle, now the Elephant is dying from overhunting. Despite being an incredibly strong creature, he has fallen to the inevitable progression of time. Worse still, soon he will be forgotten.
Christopher Okigbo
Okigbo is the narrator of several of his poems, including "Hurrah for Thunder" in which he identifies himself by name. He is a "town crier," which means he's a sort of prophet or local official who is responsible for guiding the townspeople in times of crisis and to predict the future in certain ways. Tired of being ignored, he expresses a desire to stop talking because nobody listens. He's afraid that his work is wasted and that his words are vain.
Dee Christopher
This character from "Path of Thunder" is also a town crier. He leads the unknown protagonist of this poem into the desert and abandons him in order to enact a ritual. As a crier, he is preparing to initiate this other man into the profession. Christopher expresses disdain for soldiers and violence, preferring instead to worship the gods and remain dedicated to their will.
The Lovers
In "Love Apart," this unhappy pair realizes that their relationship is doomed. As one tells the other, they think that they're together, but really they are each utterly alone. Just like the regular oscillations of day and night, they've entered the night.
