No era el más alto de su clan, ni el más fuerte, pero en sus ojos azules como el hielo de un glaciar ardía una determinación que superaba a la de cualquier guerrero. + +Erik pertenecía al clan del Lobo Gris, cuyos antepasados habían navegado hasta las costas de Inglaterra y regresado con riquezas y gloria. Pero ahora, las tierras del norte sufrían un invierno cruel que no terminaba, y el clan agonizaba lentamente. + +Una noche, mientras la aurora boreal bailaba sobre las montañas, la anciana vidente del clan, una mujer llamada Sigrid cuyo cabello blanco rivalizaba con la nieve, convocó a Erik. + +—El destino te ha elegido, joven lobo —dijo Sigrid, sus ojos ciegos mirando más allá del mundo visible—. En las montañas de Jotunheim, donde los gigantes de hielo aún caminan, yace la Espada del Lobo Gris. Forjada por los enanos en tiempos inmemoriales, su filo puede partir el hielo eterno y traer la primavera de vuelta a nuestras tierras. + +—¿Por qué yo? —preguntó Erik—. Hay guerreros más valientes, más fuertes... + +—Porque tú tienes algo que ellos no poseen —interrumpió Sigrid—. Tienes un corazón puro. La espada solo obedece a quien no busca poder para sí mismo, sino para su pueblo. + +Al amanecer, Erik partió solo hacia el norte. Cruzó valles donde el viento cortaba como cuchillo, escaló acantilados donde ni las águilas se atrevían a anidar, y finalmente llegó a las puertas de Jotunheim. + +Allí, en una cueva de hielo azul que brillaba con luz propia, encontró a la guardiana: un lobo gigante de pelaje plateado y ojos dorados. Era Fenrir, el último descendiente de los antiguos lobos divinos. + +—Muchos han venido —gruñó el lobo, su voz resonando en la caverna—. Todos han caído. ¿Qué te hace diferente, pequeño humano? + +Erik no desenvainó su hacha. No adoptó postura de combate. Simplemente se arrodilló y habló con honestidad: + +—Vengo no por gloria, ni por riquezas, ni por poder. Vengo porque mi pueblo muere de frío y hambre. Si debo morir aquí para que ellos vivan, que así sea. Pero si existe alguna esperanza... + +El lobo observó largamente al joven vikingo. Luego, lentamente, apartó su enorme cuerpo, revelando una espada clavada en un pedestal de hielo. La hoja brillaba con un resplandor plateado, y en su empuñadura de madera de fresno tallada se veía la figura de un lobo aullando a la luna. + +—Toma la Espada del Lobo Gris —dijo Fenrir—. Pero recuerda: su poder es un don y una carga. Cada vez que la uses para el bien, un poco de tu vida fluirá hacia ella. Úsala sabiamente. + +Erik tomó la espada con ambas manos. Al hacerlo, sintió un escalofrío que recorrió su espalda, como si un hilo invisible hubiera sido tejido entre su alma y el acero. + +El regreso fue más rápido. Cuando Erik llegó a su aldea, llevaba tres días sin comer y sus manos estaban congeladas, pero la espada brillaba con fuerza renovada. Se dirigió al centro del poblado, donde un antiguo monolito marcaba el corazón del territorio del clan. + +—¡Pueblo del Lobo Gris! —gritó, y su voz resonó con una fuerza que no era solo suya—. ¡La primavera regresa! + +Con un movimiento fluido, clavó la espada en el monolito. Un resplandor plateado explotó desde la hoja, extendiéndose en ondas por toda la tierra. El hielo comenzó a agrietarse, los ríos descongelaron sus aguas, y brotes verdes emergieron de la tierra que llevaba años muerta. + +El clan celebró durante tres días y tres noches. Pero Erik notó algo diferente en sí mismo: su cabello, antes oscuro como la noche, ahora tenía mechones plateados. Su rostro, aunque joven, portaba líneas de cansancio que no estaban allí antes. + +Sigrid se acercó a él mientras todos dormían. + +—El precio ha comenzado a cobrarse —dijo la anciana—. Cada gran acto de poder tiene su costo. + +—Lo sé —respondió Erik, mirando la espada que ahora llevaba siempre consigo—. Pero mi pueblo vive. Eso es suficiente. + +Los años pasaron, y Erik se convirtió en el jarl más respetado del norte. Con la Espada del Lobo Gris, derrotó a piratas que amenazaban sus costas, negoció la paz con clanes enemigos, y guió a su pueblo a través de hambrunas y guerras. Cada vez que usaba la espada para el bien, su cabello se volvía más plateado, su rostro más curtido, su cuerpo más cansado. + +A los treinta años, parecía tener cincuenta. A los cuarenta, parecía un anciano. Pero nunca dudó, nunca lamentó su elección. + +En su lecho de muerte, rodeado por su familia y sus guerreros, Erik llamó a su nieto, un niño de ojos azules como los suyos. + +—La espada te espera —susurró—. Pero recuerda: el verdadero poder no está en el acero, sino en el corazón que lo empuña. Usa este don sabiamente, y cuando llegue tu hora, pásala a quien sea digno. + +Cuando Erik exhaló su último aliento, la Espada del Lobo Gris brilló una vez más, y en el cielo nocturno, los aldeanos juraron ver la forma de un lobo plateado aullando junto a la luna. + +Así terminó la historia de Erik el Altruista, el jarl que dio su vida por su pueblo. Pero la leyenda de la Espada del Lobo Gris continuó, pasando de generación en generación, esperando siempre a quien tuviera el corazón puro necesario para blandirla. + +Porque en el norte, donde el frío nunca muere del todo, siempre habrá necesidad de aquellos dispuestos a calentar el mundo con su propia luz. + +--- + +FIN diff --git a/package.json b/package.json index 9e4889a..78022e4 100644
