Creating a plugin – Why is my table not being created upon activation?

So I’m trying to build a plugin that allows a WordPress member to create multiple role playing characters.

I’m not getting any error messages. It simply doesn’t install a the table I’ve commanded it to. I’ve checked my my WPDB in PHPMyAdmin for the table “myth_char”, but didn’t find it. Maybe it’s just something to do with the spacing. The codex seems to be pretty picky about that.

<?php
/**

//register all hooks
register_activation_hook( __FILE__, 'myth_install' );

//INSTALL

  function myth_install(){
     global $wpdb;
     global $myth_db_version;

  $table_name = $wpdb->prefix . "myth_char";

  $charset_collate = $wpdb->get_charset_collate();

  $sql = "CREATE TABLE $myth_char (
      id int(10) NOT NULL AUTO_INCREMENT,
      char_id int(10) NOT NULL AUTO_INCREMENT,
      char_name varchar(20) DEFAULT 'MAJABA' NOT NULL,
      time datetime DEFAULT '0000-00-00 00:00:00' NOT NULL,
      PRIMARY KEY myth_char_pk char_id,
      FOREIGN KEY myth_char_fk (id) REFERENCES wp_users(id)
  );";

require_once( ABSPATH . 'wp-admin/includes/upgrade.php' );
dbDelta( $sql );

add_option( "myth_db_version", $myth_db_version );

}
